Canon RF 100-300mm f/2.8 L IS USM Mirrorless Camera Lens

The Canon RF 100-300mm f/2.8 L IS USM is a landmark professional telephoto zoom lens for Canon EOS R-mount full-frame mirrorless cameras. Building on the legendary EF 300mm f/2.8 prime, it delivers the same constant f/2.8 speed across a versatile 100–300mm zoom range — making it the go-to lens for indoor sports, events, theatre, fashion, and wildlife. Dual Nano USM autofocus, 5.5-stop optical image stabilisation, and a robust L Series weather-sealed build make this a true professional tool.
